Hello !
I have been doing a lot of experimenting with Cura Tree supports, especially since they have improved in recent releases.
In my example, I am using a support test model (https://www.thingiverse.com/thing:3232756)
To keep it simple - the machine and filament are all dialed in ESTEPS, Slicer flow, retraction, Linear Advance and so on.
I'm using a 0.6 nozzle at 0.2 mm layer resolution. (The 0.6 offers me less walls but the great layers of the 0.4 nozzle)
I guess my first question for the Cura devs like @nallath - for the support Z distance, does Cura support a value of 2 decimal places? Does Cura just use 0.2, 0.3, etc or can you find tune that value to 0.25, etc. ?
I'm trying to determine the magic formula of layer height to Z Distance. I would assume closer is better but there seems to be a fine line between fused support and not great layers on top of the support roof/interface.
There are some really great videos on regular supports that I have tried to adapt for my testing. Certainly, different PLAs react differently in my testing as well.
I have also messed with the Support Interface Density and bit. 50-75% seems to work just fine.
Most of my prints are just dealing with that roof setting. I'm using the Concentric pattern since, well, I don't see any change going from that to grid?
Anyways, Cura changes rapidly and keeping up with all the improvements takes some work,.
I wanted to see if I was missing any important steps to create better supports!
